Some IP’s not ping-able...

I'm getting some very strange results when setting up a new ping check rule. It appears as though I can put in any IP address accept our web site, which makes me think it may be a routing issue, but I don't understand how or why.



I have tested the PING rule using an internal address and a couple of public addresses (eg google) which are always successful. I then tried our we site IP address (www.holiday-rentals.com - 213.86.34.164) but I always get the message "Connection to host timed out". I can PING the IP address from a command prompt on the same server with a successful response of 30mS.



I'm guessing the PING check doesn't just shell out and use that standard Windows PING utility, therefore is there a subtle difference in your implementation of PING? Or can you think of something I'm doing stupidly wrong?



I have tried this on a number of installations of ServersCheck (all on our internal LAN) and always get the same result.



Strangely, if I do a tracert check to the same IP it is successful!



Cheers, Tom

    You can always use the PINGAVG command with uses the Windows based PING command (shell out).



    This only works for English based Windows installations.

    Cheers for the work around.



    I'm guessing there's no way of finding out the cause of the failed pings...

    It is uses a built PING command. It is probably a network/protocol issue. The PINGAVG has been written to use the PING command within Windows as this one provides an average result of 3 ping calls (the other PING command is the response time of one single request)
